1N6642USE3

Overview

The Microchip Technology 1N6642USE3 is a lead-free small signal switching diode designed for surface-mount applications. It features a peak reverse voltage of 75 V and a maximum forward current of 300 mA. The device exhibits a fast recovery time of 5 ns with a forward voltage of 1.2 V and a reverse current of 25 nA. It supports a surge current of 2.5 A and operates within a temperature range of -65 °C to +175 °C.

Feature Summary

• Lead-free construction compliant with environmental standards
• Fast switching capability suitable for high-speed digital circuits
• Robust thermal performance for extended operating temperatures

Applications

• Signal processing in computer systems
• High-speed switching circuits
• General purpose rectification in compact electronics

Procurement Notes

Verify the specific suffix 'E3' confirms lead-free status and RoHS compliance during procurement. Confirm the MELF package type matches your PCB footprint requirements. Ensure the supplier provides official Microchip documentation to validate authenticity and manufacturing origin before finalizing orders.

Selection Notes

Select this component when a compact SMT switching diode with fast recovery characteristics is required. The 75 V rating suits low-voltage logic interfaces. Consider the 5 ns recovery time for high-frequency applications where standard diodes may introduce excessive delay or heat.

Part Context

This part belongs to the 1N6642 series of small signal switching diodes manufactured by Microchip Technology. The 'USE3' designation indicates a surface-mount variant in a MELF-style package with lead-free plating, distinguishing it from through-hole or older tin-lead versions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify pinout compatibility and electrical ratings if considering alternative manufacturers without official substitution lists.
